Abstract
The invention discloses a method for shaping fan blades. The mold comprises a mold mother body and fan blade injection molding grooves disposed on the mold mother body. The mold mother body is provided with water flow through holes; two ends of the water flow through holes are connected with water flow through pipes; and the mold mother body is provided with a heating module. The mold has the advantages that the shaped fan blades have high quality and the shaping speed of the fan blades is fast.
Description
Technical field
The present invention relates to a kind of mould, relate in particular a kind of mould for the fan blade moulding.
Background technology
Fan leaf is complex-shaped, wall unevenness, and dimension precision requirement is higher, and it has higher surface quality and dimensional stability requirement.Fan leaf is plastics mostly, and it generally adopts injection molding mode to make.And injection moulding has following advantage: almost do not have limitation of complexity, allowing has different thermoplastic piece plastics in the mould; To the quality of plastic without limits; In uniform temperature, has suitable mobile thermoplastic; The high-precision plastic of injectable has preferably surface quality and dimensional stability etc.Adopt injection molding mode, it can adopt mould.But mould adopts metal material, and after the thermoplastic piece plastics were to the mould parent, the die male body was exerted pressure to the mould parent, and it is not easy to heat radiation, and the typing speed of fan leaf is slow.
Summary of the invention
The invention provides a kind of mould for the fan blade moulding, the quality of the fan blade of its typing is high, and the typing speed of fan blade is fast.
For solving above-mentioned technical problem, the present invention by the following technical solutions:
A kind of mould for the fan blade moulding, it comprises mould parent and the fan blade injection slot that is arranged on the mould parent, be provided with the current through hole on the described mould parent, the two ends of described current through hole are connected with the current siphunculus, are provided with heating module in the described mould parent.
The thermoplastic piece plastics are cast in the mould parent, and its temperature is higher, because the thermoplastic piece plastics could be finalized the design at a certain temperature, allow it naturally cool off, and efficient is certainly not high.In the present invention, at the mould parent current through hole is set, in the current through hole, passes into cold water by the current siphunculus, by flowing of cold water, take away the temperature on the mould parent, accelerate the typing speed of thermoplastic piece plastics, namely accelerate the typing speed of fan blade.Because the material of the plastics that fan blade is used, in order to make when the thermoplastic piece plastics are carried out injection moulding, the thermoplastic piece plastics that stick on the mould parent can not finalized the design moment, guarantee that the thermoplastic piece plastics have good flowability, heating module can preheat the mould parent, makes the temperature of mould parent reach certain value, guarantees that the thermoplastic piece plastics are at the injection moulding initial stage, can not solidify moment, to guarantee the quality of fan blade.
Further technical scheme is:
For the time heating module rate of heat addition of mould parent is effectively improved, described heating module is positioned at the bottom of fan blade injection slot.Heating module only needs that the fan blade injection slot is heated to certain temperature and gets final product when the mould parent is heated, and is about to heating module and places fan blade injection slot bottom that the rate of heat addition is improved.
Be provided with die male body fixed bolt hole on the described mould parent.Mould parent and die male body match and can become fan blade with thermoplastic piece is plastic injection-moulded, and die male body fixed bolt hole is used for the public body of fixed mould.
The distance of described die male body fixed bolt hole and fan blade injection slot is less than the distance of current through hole and fan blade injection slot.
In order further to accelerate the loss of thermoplastic piece plastics temperature in the mould parent, described current through hole has a plurality of, and evenly be arranged on the fan blade injection slot around.
Described current through hole has 8 at least.
Described heating module is resistance wire.Adopt resistance wire that the mould parent is preheated, namely adopt electrically heated mode, its cleaning, simple in structure, adjustable extent is large, is convenient to the control to temperature.
Compared with prior art, the invention has the beneficial effects as follows:
1, pass into cold water in the current through hole of the present invention, can accelerate the cooling rate of thermoplastic piece plastics in the mould parent, be conducive to the fast shaping of thermoplastic piece plastics, the time fan blade injection moulding efficient be improved.
2, be provided with heating module in the mould parent of the present invention, heating module can preheat the mould parent, and part thermoplastic piece plastics solidify in the fan blade injection slot when avoiding injection moulding, can guarantee the quality of fan blade injection moulding.
Description of drawings

Label among the figure is: 1, mould parent; 2, fan blade injection slot; 3, current through hole; 4, current siphunculus; 5, die male body fixed bolt hole.
The specific embodiment
The present invention is further illustrated below in conjunction with accompanying drawing.Embodiments of the present invention include but not limited to the following example.
[embodiment]
A kind of mould for the fan blade moulding as shown in Figure 1, it comprises mould parent 1 and the fan blade injection slot 2 that is arranged on the mould parent 1, be provided with current through hole 3 on the described mould parent 1, the two ends of described current through hole 3 are connected with current siphunculus 4, are provided with heating module in the described mould parent 1.
Described heating module is positioned at the bottom of fan blade injection slot 2.
Be provided with die male body fixed bolt hole 5 on the described mould parent 1.
The distance of described die male body fixed bolt hole 5 and fan blade injection slot 2 is less than the distance of current through hole 3 with fan blade injection slot 2.
Described current through hole 3 has a plurality of, and evenly be arranged on fan blade injection slot 2 around.
Described current through hole 3 has 8 at least.
Described heating module is resistance wire.
Be as mentioned above embodiments of the invention.The present invention is not limited to above-mentioned embodiment, and anyone should learn the structural change of making under enlightenment of the present invention, and every have identical or close technical scheme with the present invention, all falls within protection scope of the present invention.
